Analysis of the volatile constituents of flos chrysanthemi indici in Yangling demonstration zone of Shaanxi by SPME/GC/MS / 国际中医中药杂志

ABSTRACT

Objective@#To analyze the chemical constituents of the volatile constituents of Flos chrysanthemi indici.@*Methods@#The volatile constituents in Flos chrysanthemi indici was extracted by the method of Solid phase microextraction (SPME). The components of the volatile constituents were separated and identified by gas chromatography-mass spectrometry (GC-MS). The relative content of each component was determined by area normalization.@*Results@#Fifty different compounds were isolated and identified, accounting for 97.17% of the total volatile constituents. The main components in volatile constituents of Flos chrysanthemi indici were eucalyptol (24.72%), á-Myrcene (15.78%), 1,6,10-Dodecatriene, 7,11-dimethyl-3-methylene-, (Z)- (10.44%), Camphor (10.05%), Naphthalene, 1,2,3,4,4a,5,6,8a-octahydro-7-methyl-4-methylene-1-(1-methylethyl)-, (1à,4aà,8aà)- (4.81%), á-Phellandrene (4.43%), 1R-à-Pinene (4.28%), Bornyl acetate (2.56%), Bicyclo [3.1.0] hexane, 4-methylene-1-(1-methylethyl)- (1.59%), 1H-Benzocycloheptene, 2,4a,5,6,7,8-hexahydro-3,5,5,9-tetramethyl-, (R)-(1.47%).@*Conclusions@#The SPME technology can be used for volatile component analysis of wild chysanthemum,and it can help to improve the sensitivity and accuracy.
